3.
The system receives 8 bytes of serial data.
4.
The system enters normal incremental operation status about 50 ms after
the last serial data is received.

Absolute Data
The following table shows phase-A serial data specifications for absolute
data.
Phase-A Serial Data Specifications
Serial Data
During normal operation, the number of revolutions (5 digits) from the refer-
ence position (specified at setup) is output as serial data in the above format.
Zero revolutions are output as “P+00000(CR)” or “P–00000(CR).” The number
of revolutions exceeding
±
99999 will not be output correctly. In other words,
after exceeding
±
99999, the number of revolutions will return to 00000.
